IATA DGR Study Guide: Trace the Consignment Method

The IATA Dangerous Goods Regulations reward one study habit above others: tracing a single consignment from classification to acceptance, chapter by chapter. The manual is a layered, cross-referenced decision system — a hazard decision feeds a shipping name decision, which feeds a packaging pathway, which feeds documentation, all filtered through State and operator variations. Studying isolated tables breaks those chains. This guide teaches the named decision points, works through two realistic consignments, and gives a scoring rubric plus a six-week sequence you can adapt to any DGR-based syllabus.

Separating classification from proper shipping name selection

Classification and proper shipping name (PSN) selection are two distinct decisions with different inputs. The shipper owns both. Classification asks what hazard exists; PSN selection asks which regulated identity governs the UN number, packing group, labels, and packing instruction.

The Regulations place responsibility for correct classification on the shipper, with the criteria for each class and division set out in the classification section of the DGR. Where a product's status is unclear, the shipper can seek advice from the manufacturer or distributor, have testing performed by an accredited laboratory, or consult the competent authority. Treating that responsibility as a decision procedure — gather evidence, apply the criteria, document the outcome — turns a vague duty into a repeatable study target.

Keep the vocabulary separate in your notes: a class is a broad hazard type, a division is a subdivision of certain classes, and a packing group ranks relative danger within some classes. A single product raises three questions — is it dangerous, which class or division applies, and how dangerous within that class. Answer them in that order, because the packing group you record on the Shipper's Declaration follows from the class decision, not from the shipping name alone.

Using the List of Dangerous Goods as a routing tool, not a memorization list

The List of Dangerous Goods works as a decision tool: each row chains a UN number, PSN, class or division, packing group, labels, and a packing instruction. Practice reading that chain forward and backward rather than memorizing rows.

Take one row and trace every cross-reference it contains: the special provisions that modify the entry, the packing instruction the row points to, and any note that restricts the entry to a specific state of the product. Adjacent entries often differ by a single condition — how the article is contained, whether it is new or damaged — and the correct choice changes the packing instruction and label set downstream. Reading rows this way builds the lookup skill that both the exam and real acceptance work demand.

A focused drill: pick three neighboring entries for the same commodity family and write one sentence per entry explaining the condition that separates it from its neighbors. Entries covering lithium ion batteries shipped alone, contained in equipment, or packed with equipment describe three different consignment structures, and mixing them up changes everything from the PSN on the declaration to the packaging allowed. If you cannot state the distinguishing condition, you have not learned the entry — you have only recognized it.

Choosing between UN specification packaging and Limited Quantity provisions

Limited Quantity provisions do not permit an ordinary cardboard box. They require combination packaging — inners meeting the relevant construction criteria and an outer built to the same kind of criteria as UN specification packaging — proven by drop and stacking tests.

Under the Limited Quantity provisions the fiberboard outer must meet the applicable construction criteria, and the packed package must withstand a 1.2-meter drop, in the position most likely to cause damage, without leakage, plus a 24-hour stacking test without breakage or leakage. Most general packaging requirements still apply; a short list of exceptions is spelled out in the general packaging provisions. The main difference from UN specification packaging is the testing basis, not the construction standards themselves.

Study packaging by asking three questions per shipment: which pathway applies, which construction criteria govern the inner and outer components, and what performance evidence supports the package. Appendix F of the DGR lists suppliers of UN specification packaging, which helps you see what a compliant pack looks like commercially. The table below places the pathways side by side so you can rehearse the decision rather than recall it.

Reconciling the ICAO Technical Instructions, the DGR, and State/operator variations

Air transport rules arrive in layers: the ICAO Technical Instructions set the baseline, the DGR restates them as an airline-recognized field manual with somewhat stricter, more precise requirements, and Section 2 variations add State- and operator-specific rules.

IATA develops the DGR with governments and ICAO, and describes it as a field-manual version of the Technical Instructions, written in an easy-to-interpret format by airline dangerous goods experts, with additional detail that helps shipments pass acceptance quickly. Because IATA airlines apply requirements somewhat stricter than the Technical Instructions in places, the DGR specifies more precisely how to prepare a consignment. Study the two documents as baseline and applied layer, not as rivals.

Worked scenario: a forwarder tenders a flammable liquid consignment to Paris that meets every base rule, and the airline still refuses it. The plausible mistake is treating the manual as one flat rule set and never opening Section 2. The better decision: list every State and operator on the itinerary, check each variation (for example, France carries variation FRG-07, and some Japanese carriers have their own IDs such as JL-11), and remember that paragraph 1.2.4 lets carriers decline any substance and impose extra requirements. Why it matters: acceptance is checked against itinerary-specific rules, not the base text alone.

Shipping lithium batteries: the Section II pathway and UN 38.3 verification

Lithium batteries are dangerous goods, but how they travel decides the pathway: Section II of the applicable packing instruction may remove the need for a formal declaration, provided the cell or battery meets UN 38.3 testing.

Worked scenario: a shipper's paperwork for equipment containing lithium batteries is copied from a competitor's declaration showing the 'packed with equipment' entry, even though the batteries sit installed inside the devices. The plausible mistake is cloning a UN number and PSN without checking the consignment's actual structure; 'contained in equipment' and 'packed with equipment' are different entries driving different instructions. The better decision is to inspect the shipment first, select the entry that matches it, then check whether Section II of that packing instruction fits the quantities involved.

Verifying UN 38.3 compliance is its own step: ask the manufacturer or distributor for recent production information, which may appear in product data sheets or on their websites. Safety data sheets are not required in transport and not required at all for articles, and many SDS documents do not carry accurate transport classifications — so do not treat an SDS as the deciding evidence. Also expect the rules to move: ICAO issued a 2026 addendum on power banks carried by passengers and crew, so recheck the current edition and addenda before finalizing any battery shipment.

Documentation details you can verify field by field

Documentation rewards verified detail. IATA recommends a 'full address' meaning a physical location the postal system in that country could deliver to; abbreviations such as USA, TX, or NSW are acceptable. Every declaration field should trace to an earlier decision.

There is no formal definition of a full address in the DGR, which is why the recommendation matters for study: think deliverable, not formatted. An address indicating a physical location acceptable in the post in that country satisfies it, and standard abbreviations are fine. Practicing this detail teaches a broader lesson — when a term feels undefined, look for the issuer's published guidance and apply its intent rather than inventing a stricter private rule.

Treat the Shipper's Declaration as the output of the decision chain, not a separate subject. The UN number, PSN, class or division, packing group, and packing instruction you record must each match the entry you selected and the pathway you chose in earlier chapters. A study method that practices documentation in isolation from classification invites mismatched fields; instead, draft the declaration only after completing a written classification worksheet, and check each field against the manual location that justified it.

A trace-the-consignment exercise and six-week study sequence

Readiness grows from weekly end-to-end traces: classify a product, select its entry, choose a packaging pathway, check variations for two carriers, and draft the documentation. Score yourself against the rubric below; treat a high score as a learning milestone only.

Run the exercise with a hypothetical consumer flammable liquid whose safety data sheet omits transport information. Worked steps: apply the Section 3 criteria to the product's properties; select the PSN that matches; decide between UN specification and Limited Quantity packaging using the testing evidence available; pick two carriers on the route and name their variation IDs; draft the declaration. Expected observations: you stall exactly where your knowledge is thin, and a correct trace produces a declaration in which every field cites a manual location.

A six-week adaptable sequence: week one, regulatory framework and classification criteria; week two, List of Dangerous Goods drills with adjacent entries; week three, packaging pathways, construction criteria, and Appendix F; week four, lithium batteries and UN 38.3 verification; week five, State and operator variations plus documentation; week six, full timed traces and a review of the current edition's addenda. Compress or extend the weeks to match your syllabus weightings, but keep one full trace every week.

RUBRIC

• Classification (0–2): correct class or division, with the deciding criterion cited.
• Entry selection (0–2): chosen PSN justified against neighboring entries.
• Packaging (0–2): pathway named, construction criteria identified, testing basis stated.
• Variations (0–2): variation IDs listed for two carriers on the itinerary.
• Documentation (0–2): every field traces to a prior decision and a manual location.
• Milestone: consistent 8–10 on fresh traces before exam day; a lower score identifies chapters to reread, not predicted performance.
